Cycles rendering mystery - Character completely dissappears

Hi - I’m at a huge loss here. Workflowed a character from DAZ3D to Marvelous Designer to Blender. Nothing I haven’t done before.

I test render through every step of my process and all was looking well and fine, until after I was done with my hair particle work (yes, I still use the old system, no I probably won’t go to the new one for a minute sorry). From this point onwards, my character dissappears in the render - but not in the viewport (see screen shots)!!! I’ve never seen something like this happen before and am going crazy trying to trouble shoot this.

Any IDEA???

Hi, i presume you have checked that nothing is switched off in the outliner
We need to see a screenshot of your outliner and the ui setup.
